I have been teaching my self to "code" in the android language and java over the past few day. So I am new to this so please be patient.
Basically, my problem is I am trying to get a button on my form to open a web page.
Here is my java file.

Let's say I have a few buttons in a LinearLayout, 2 of them are:
mycards_button = ((Button)this.findViewById(R.id.Button_MyCards));
exit_button = ((Button)this.findViewById(R.id.Button_Exit));
I register setOnClickListener() on both of them:
mycards_button.setOnClickListener(this);
exit_button.setOnClickListener(this);
How do I make a SWITCH to differentiate between the two buttons within the Onclick ?

So far I've only found examples where they start a configuration activity from a widget button. Does someone have example code on using buttons in home screen widgets?
View 4 Replies View RelatedIn my application i have a button initially on the screen and in onclick of the button ,popup window should open. In the popup window i have an imagebutton , now on click of this button i want to start an activity. The popup window opens but i dont understand how to handle the onclick of the imagebtn inside popup window.
In main.xml i have a button and in popup_example.xml i have an imagebutton.
Java code is as follows:

My 1.6 app works fine in both portrait and landscape modes on the default HVGA device. I'm now trying to support it on QVGA devices and am encountering build-time errors I don't understand. In my res/drawable-ldpi directory I have:
startstopin.png startstopout.png and a selector file
startstopbuttonimageselector.xml
which contains:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:drawable="@drawable-ldpi/startstopin" />
<!-- pressed --> <item android:drawable="@drawable-ldpi/startstopout" />
<!-- default --> </selector>
I've 'fixed project properties' and done a 'clean' build, to no avail. The error I get is:
Error: No resource found that matches the given name (at 'drawable' with value '@drawable-ldpi/startstopin').
Error: No resource found that matches the given name (at 'drawable' with value '@drawable-ldpi/startstopout').
I've tried adding a layout file in res/layout-small that explicitly references this selector file, but this triggers a similar build error and fails to address the original problem:
Error: No resource found that matches the given name (at 'src' with value '@drawable-ldpi/startstopbuttonimageselector').
just a short question for a better understanding: I'm developing an app based on the Android 1.5 Framework (with compatibility down to 1.1). But now I read about the new way of implementing click-handlers in Android 1.6 on the Android Developer Blog and I'd really like to use that in my app because it makes developer's life so much easier :) But can I use this (and the 1.6 Framework) without losing backward compatibility to 1.5 and 1.1? Best regards and sorry if this question is dumb [I just didn't find anything via google]
View 2 Replies View RelatedI know how to set a listener for.. let's say a button or a editext so that when clicked some action happens:
buttonOReditextl.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { Action goes here } });
how can I set a onClick event for when the user taps/ clicks on the screen? or the surface.. I'm not sure? I want a picture to be taken when the camera is on.. but don't know how to make a listener to all the camera view instead of having a button to take a picture.

View 4 Replies View RelatedI am trying to create a list view where each item will open up a new view and display a picture and text describing the item when said item is selected. I am working with this tutorial novice-tutorials-f8/opening-windows-i-e-webbrowser-reacting-on-clicks- t22.html?hilit=reacting%20on%20Clicks
so is there a way i can use this code to open up a new view
[code]@Override protected void onListItemClick(ListView l, View v, int position, long id){ super.onListItemClick(l, v, position, id);
// Get the item that was clicked Object o = this.getListAdapter().getItem(position); String keyword = o.toString();
// Create an VIEW intent Intent myIntent = null; // The intent will open our anddev.org-board and search for the keyword clicked. myIntent = new Intent("android.intent.action.VIEW", Uri.parse ("" + keyword + "")); // Start the activity startActivity(myIntent);}
I have a DialogPreference in my Preference Activity and would like to know which button was pressed. I have implemented the OnSharedPreferenceChangeListener which does not seem to get triggered when the DialogPreference is selected. I have also tried OnPreferenceClickListener but this gets triggered as soon as the DialogPreference is clicked from the main screen and not when one of the actual dialog buttons was pressed. I think I need to implement onClick for this dialog but I am not sure where to do this. I have looked at the API Demo code and it shows how to create the dialog but not how to determine which button was pressed.
public class Preferences extends PreferenceActivity implements OnSharedPreferenceChangeListener {
private static final String LOG = "test"; private DialogPreference mfactory;

View 2 Replies View RelatedI guess this is kind of an odd question but i have tried setting onClicklistener on an ImageView and it has worked. But the problem is that the user cannot sense the click. I mean if some of u have worked on other mobile environs(like apple iphone) then wen we click on a Image in other environs then it gives an effect on the image so that the user can understand that the image has been clicked.
I have tried setting alpha using "setalpha" method but it doesnt work. Though the same thing is working fine on onFocusListener implementation. Can some1 suggest a different way to modify the image on click...

I have 3-4 activities in the application and all of them have some event listeners that work nicely.
However only on one activity i simply can't get the event handling to work.
I tried the solution from this thread:http://www.anddev.org/view-layout-resource-problems-f27/ontouch-not-called-t16578.html
It doesn't work for me. I tried to manually set OnClickListeners for ImageViews from java code, android:onClick from XML.
It seems that some other component handles all the events, or my activity doesn't have some permission to handle events.
Should I put something in the AndroidMainfest.xml for my activity that enables handling events?
Hope someone has the idea what should i try, here's the code:

I have two onclick method in android project
CODE:...............
And i have onther onClick method in which i have to call that method directly
CODE:..............
I have an Activity that implements a Gesture Detector to catch the user fling input for navigation to other screens. That was working fine - but - I recently updated a class that derives from my BaseActivity to add an onClick function and now that click event seems to block the onFling from being hit. The onClick is tied to a TextView area (in a LinearLayout) I have on my screen. The resultsClick method is wired to the TextView using its onClick property in the XML layout.
I've tried changing the return values in onSingleTapUp and onDown without luck. I've also tried adding log statements to all the functions below as well. None of them fire when I fling in the TextView area but they do on other areas of the screen.
Maybe I am using the wrong search terms, but I couldn't seem to find an example that addressed this - yet I'm sure this problem has been solved before.

I've spent over a week trying to figure out a way to do a Limited Multi Selection Preference list. Nothing I've tried works. I'm ready to give up on Android if something seemingly simple is so hard. I've been programming a long time and don't remember being beaten up this badly by something like this. I have to assume I am not understanding something basic. I hope someone can point me in the right direction.
Here is the simplest code I can think off that should work. It does not clear the checkbox even when setting it to false, I've tried true as well. Why doesn't that work? If that will not work, what will?

I'm in a process of creating a memory game. My problem is that whenever i click for the second time, i can't even see toggled button. To be clear - first click toggles the togglebutton, so i can see the number it holds, the second click on a different togglebutton is suposed to toggle it, show me the number and then proceed to either set a score +1 if numbers are the same, or reverse them back again if they're different.
Below is the code that i use as my onClick function, i've been thinking about putting some kind of sleep or delay function somwhere in the second "if block" - (if(klikniecia ==2)).

I think, about setting a delay here, so i can see both of the cards, regardles if the're the same or not before reverting them.

I am working on my first android app and so my first with the Maps API and am experiencing an odd problem. How ever when I click the screen it seems the onClick event is not being run?Have I missed something or am I better off sub classing the MyLocationOverlay I am using and override DispatchTap?How ever i would rather be able to just click anywhere on the map to dispatch the event.
